APPARATUS FOR MAKNG FIXTURES FOR SHADE ROLLERS.

Application filed July 24,

This invention relates to apparatus vfor making shade roller attachments of the class set forth in my Patent 912,636, .issued February 16, 1909 in which a pair` of opposed catch plates are slidably mounted upon a supporting disk which is secured to lone end of the shade roller so that as the roller is `rotated the catch plates are free to move into and out of engagement with the teeth of the usual relatively stationary pintle. 1

'The main object of the present invention is to provide means forautomatically formy vtionof the sheet metal strips from vwhich the catch plates are formed showing thesuccesing and assembling the catch plates and their supporting disk from continuous strips of sheet metal as they are automatically fed into the machine. In other words, I have sought-to successively stamp the blanks for the ysupporting disk from one continuous trip of sheet met-al; to successively stamp the catch plates from a pair of'continuous parallel stripsofsheet metal, to deposit the catch plates in pairs j upon each supporting disk as the catch plates and disk blanks are successively formed; to bend the guide anges of the supporting disk across adjacent portions of the plates;

Vto simultaneously bend the four corners of' the supporting disk into position for attachment to the roller, and to finally expel the completed attachment as the parts therev of areassembled.'l f u Other objects and uses relating to specific parts of the apparatus will be brought outV in the following description.

The die block %3l% on the lower end of the plunger V%l% is provided with a plurality of, in this instance three, male dies %t2%, %d3% and %4l% arranged in uniformly spaced relation in sequence l from front to rear of the supporting block 34% and adapted to cooperate with a corresponding number of companion female dies l-5%, %@l6% and %47% :on thev underlying block y f%38% to form what may be termed the disk blank shown in Figure 12 for receiving and supporting the catch plates shown inFigurcs 15 and 16;

The distance between the-centers ofthe cooperativevdiesis slightlygreater than the length of the vdisk` blank sol that the latter maybe stamped from a stock strip as %A- of sheet metal without material waste. a

. A guide 1%48% is mounted in a horizontal, position upon the upper face of the die block -38% so as Yto extend transversely thereof across the female dies %45%, 46% Y andy %4:7% and .is `provided with vertical openings therethrough i ,for receiving lthe male dies %l2%', and-%44-%.

V,' Ihe'sheet meta-l strip %A% is fed lengthwise intermittingly step by step through f the guide 48% one die space, at a time in thev direct-ion indicated by arrow %m%, Figure 3, and at each period of rest the plunger %1% and male dies carried thereby are pressed downwardly into co-action with the .o

corresponding female dies to form the blank shownjin Figure 12 and to simultaneously formthe central opening inthe portion-of the strip which is forming thenextv succeedingblank. i

That is,` the fpunching dies and %l5% cooperate to form a relatively small.

cylindrical opening as %af%ccntrally in the y c strip %A% at one period of rest of said strip. 4 l l At the next periodof rest the hole %a/%, previouslymade, is enlarged and countersunk by the next succeeding dies 43% and %46%.

L

The cams -9- and -14- are constructed 'i and arranged Vto alternately and positively depress and elevate the plunger 1- withoutobjectionable lost motion at each c-omplete reyolution of the corresponding shafts -8- and 13- and at the saine time to` allow the plunger to dwell in its uppermost position during practically one-half revolutov advance the strip -A- one die space,

/ it` being understo-od that when the plunger is being depressed the feed rolls 5G-'and -50w and strip -A- will be at rest.

A pair of punches *4W-w, Figure 17, are also mounted upon the die holder S4- at opposite sides of the punch -42-f for makn ing relatively small holes ,-6- in correspending portions of the strip -Af so as "to facilitate the formation of a substantially seniicircular groove or channel -bin lguide* '-elS- for the strip i the plate -A-- for receiving the Yadjacenty spring commonly used end of the :re-winding in Vshade rollers.

d The pair of sheet metal strips --B- are arranged edge to edge and in that rel-ation are intermittingly fed. step by step through theguide -l8- a distancel corresponding to the distance y between centers of 'the punches --59-'l and 60'- at each inevenien-t, said'strip `-B- being fed in a direction opposite to that ofthe strip A- or in the direction indicated Figures 3 and 9. l y This interinittentstep by step lengthwise movement of the strips -B- is preferably effected `by means of separate pairs of rollers 63-l and 6W-,Fig 9, those of each pair being arranged'one over the other, the lower rollers being provided with axially Vspaced Vflanges for engaging the outer longitudinal edges of the strips -B- andthereby holdingtheir inner adjacent edges in contiguous relation as the strips are fed through the Y The rollers-BB- andi-GSvof eachV l pair are geared to eachother for positive `rotation byV gears N64-1 i ,y

Intermittent rotary motion is transmitted to the lower front feed roll -634 through the mediumof a disk 65- on the outer end of the shaft-13* opposite the disk -'57-, said disk being eccentrically connected to one iis end of a pitman -66- having its other end i connected to anoscilla-ting arm 67H which is loosely mounted on the adjacent end of a separate lengthwise shaft --68-dv which is journaled in suitable bearings in the main frame coaxial with the shaft 50- as shown in Figure 3. j

The outer end of the shaft -68- is pro-r vided with a'ratchet wheelv '69- adapted to be engaged by a pawl T0-- on the outer end of the oscillating arm -67- for rotating the shaft -68- as the pitman -66- is i moved endwise by the rotation of the disk -65-,- said pitman being adjustably connected to its disk to vary the throw vof the oscillating` arm 67- Vand therebyrto vary the angular movement of the feed rollers -V-63- and resultant feed of the strips -B- at each operation.

YThis angular movement of the. feed roll `and -63- is adjusted to feed the strips -B- a distance corresponding to the spacing of the male dies--Q- and --60 and their corresponding female dies-e61- The diesf 59M are employed. to punch openings as -7 in the: strip lafter different portions thereof are registered with said dies during successive movements there- ;by forming similar but reverse half openings Qin the adjacent tedges' of each, of the strips -B-. i

The dies -GO-i 'and 6.2- serve to block out the previously perforated portions' of .the 'strips to-form the catch plates -B- thereby formingv additional openings as -'Z --in the strip -B#. 1 e

The blanl -A-' is formed with opposite end flanges ,-a- Vopposite side flanges -a and corner spurs of, all of which .are to be bent at an angle tothe main body forreitaining andguiding the catch plates and for fastening the disk to the shade rollers. l
